Add an internal "cmake -E __run_iwyu" mode to wrap the compiler call.
Run a given include-what-you-use command line with the compiler options
and report a warning if it finds anything. Then run the real compiler.

Our <LANG>_COMPILER and <LANG>_<TARGET_TYPE>_LINKER rule generation has
access to a specific cmTarget so the results may depend on it. Instead
generate separate rules for each target using an encoded target name.
In particular, this makes CTEST_USE_LAUNCHERS report proper target
information.

115e9199 Use new top-level check abstraction.
c5059c90 cmLocalGenerator: Add abstraction to check if top-level.

3837c483 Tests: Add case for 'ctest' run with bad CTestTestfile
b317b38d cmGlobalBorlandMakefileGenerator: Do not inherit from NMake generator
94867698 Don't use a cmLocalGenerator instance to call static methods.
...
If the CMakeLists.txt file does not exist, there must be a parent.
The case for the top-level of the project is already handled in
cmake::DoPreConfigureChecks.
The Borland generator re-implements every method the NMake generator
does, so there is no reason to inherit this way. Instead inherit
directly from cmGlobalUnixMakefileGenerator3 like all the other
makefile generators do.
KWSys upstream added an attribute to export .gitattributes so that
importing snapshots into the sources of other projects would bring along
the attributes. However, we don't want to export them from CMake.
Drop .gitattributes entries not relevant to CMake.
Teach the legacy two-argument signature to use CMAKE_CONFIG_TYPE
from the environment only if it is non-empty. This makes behavior
consistent with the main signature.
The find_package command, on Windows, has always searched build trees
recently visited by cmake-gui (or CMakeSetup at one time). This was
done when the command was created with the intention of simplifying
workflows involving building multiple dependent projects. However,
this behavior depends on recent developer interaction and therefore
can create different find results based on transient system states.
It can lead to surprising results and user confusion.
Since this behavior was first added CMake has gained many more search
options, better error messages when a package is not found, and a
package registry. The latter in particular allows projects to make
their build trees available for dependent projects to find without
user intervention. Therefore the originally intended workflow can
be achieved in other, more stable ways.
After the above evoluion of find_package we have now decided that
the magic search-where-cmake-gui-was behavior does more harm than
good. Drop it. We do not need a policy for this behavior change
because it only affects interactive use.
The GNU 4.8 standard library's cstdio header is not aware that C++14
honors C11's removal of "gets" from stdio.h and results in an error:
/.../include/c++/4.8/cstdio:120:11: error: no member named 'gets' in the global namespace
Detect this problematic case and default to using C++11 instead of
C++14 for building CMake itself.
